Experimental studies of reinforced concrete structures of hydraulic structures strengthened with prestressed transverse reinforcement

Utilising confinement reinforcement for shear resistance in reinforced concrete structures

Common transverse reinforcement of reinforced concrete members with circular cross-section consists of round ties or spirals. Its purpose in members that are not subjected to significant shear loading is to provide proper confinement for concrete, and eliminate buckling of the longitudinal reinforcement bars. If spirals are to be used as both shear enabler and confiner for reinforced concrete b...

Materials and Methods for Corrosion Control of Reinforced and Prestressed Concrete Structures in New Construction

FOREWORD Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly become a considerable economic burden to many State and local transportation agencies. Since the iron in the steel has a natural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still be with us, but to a much lesser degree due to the use of various corrosion prot...

A Numerical Approach for the Seismic Analysis of Reinforced Concrete Structures Environmentally Damaged and Cable-strengthened

The paper deals with a numerical analusis for the seismic response of reinforced concrete structures containing cable elements. The cable behaviour is considered as nonconvex and nonmonotone one and is described by generalized subdifferential relations including loosening, elastoplastic fracturing etc. effects. The problem is treated incrementally by double discretization: in space by finite el...

Seismic Retrofitting RC Structures with Precast Prestressed Concrete Braces- ABAQUS FEA Modeling

Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...
